EV Fast Charging for Micromobility Patent Landscape
The EV fast charging for micromobility patent space is highly concentrated, with the top five filers accounting for 97% of activity among the hundred largest filers, and the University of Toronto holding the single largest portfolio. The field is in a growth stage on a multi-year basis, though annual volume has eased from its 2018 peak and the most recent filing years remain understated by publication lag.
University of Toronto leads a tightly held, early-stage field
The University of Toronto holds the leading position among all filers, with Eleappower Ltd ranking second. The top of the ranking is dominated by a small cluster of academic and startup actors rather than large automotive OEMs.
Concentration is extreme: the top five filers account for 97% of patent records among the ranked applicants visible in this query. There is a steep drop from the top two applicants to the remaining ranked entities, indicating a two-tier structure with very limited mid-tier presence.

The leaders’ positions suggest that foundational IP in on-board fast-charging architectures and bidirectional power conversion for micromobility is being established primarily by a Canadian academic-startup ecosystem, with U. S.-domiciled energy management firms (Fermata Energy) occupying a distinct vehicle-to-grid niche.
The most recent filing years (2024–2026) are subject to publication lag and likely undercount actual activity; the overall corpus of 20 patent families should be read as a nascent but active field rather than a mature one.
Multi-year growth persists, with propulsion electronics dominating the technology mix
Annual filing activity has been irregular since 2018, with the multi-year window still showing positive growth; the technology mix is anchored in electric vehicle propulsion and power supply systems, with several adjacent branches remaining sparse.
Annual filing trend
Activity peaked in 2018 at eight patent records, then settled into a lower but persistent rhythm through 2022–2024. The field is still expanding on a multi-year basis (recent three-year filings sit well above the prior three-year window), though annual volume has eased from the 2018 peak. Figures for 2024–2026 are understated by publication lag and should not be read as a real decline.
↗ Hover for values · click a bar to ask EurekaTechnology composition
B60L (electric vehicle propulsion) and H02J (power supply and grid systems) together account for the largest shares of patent records, reflecting a focus on charging electronics and vehicle-grid integration. H02M (power conversion) is the third-ranked branch. Lower-activity branches such as H02P (motor control), H05K (printed circuits), and G05B (control systems) signal areas where the foundational EV charging work has not yet been extensively applied to micromobility-specific architectures.

What the patent structure means for R&D investment decisions
The combination of high concentration, growth-stage dynamics, and a narrow set of active jurisdictions creates both entry barriers and visible white space for new entrants with differentiated technical approaches.
Growth stage — multi-year expansion, annual volume eased from 2018 peak
The lifecycle evidence classifies this field as Growth, with the recent three-year filing window sitting well above the prior three-year window. Annual volume has eased from its 2018 peak, and the most recent years are further understated by publication lag. Foundational IP is still being established, meaning late movers face a narrowing but not yet closed window to stake claims in core sub-areas.
Growth stageTop five filers hold 97% of records among the hundred largest — extreme consolidation
With 97% of patent records among the top-100 filers held by just five entities, this field has almost no mid-tier presence. The leading two applicants — University of Toronto and Eleappower Ltd — together account for the visible share of the corpus. Any new entrant must either differentiate technically from these players or seek licensing from them to operate in the core B60L and H02J spaces.
Extreme concentrationUniversity of Toronto anchors the most active co-filing relationships
The University of Toronto has the two most active co-filing relationships in the corpus: seven joint filings with Havelaar Canada Industrial R&D Lab Ltd, and two with Eleappower Ltd. This academic-industry cluster is the primary locus of collaborative IP development in the field, suggesting that partnership with or proximity to this Toronto-based ecosystem is a meaningful accelerant for new entrants.
Academic-industry clusterU.S. leads filings; Canada and Europe are secondary; Asia absent
The United States is the primary filing jurisdiction, followed by Europe (EPO) and WIPO (PCT) with equal representation, then Canada and India. The absence of filings in major Asian EV markets — notably China, Japan, and South Korea — is a structural gap that may reflect the current applicant mix (North American academia and startups) rather than a deliberate strategy. For companies targeting Asian micromobility markets, the IP landscape there appears largely uncontested based on available evidence.

Assignee snapshot from the current evidence set
The applicants below are visible in this query result. Because the evidence set is relatively small, read this section as a directional snapshot rather than a full competitive ranking.
University of Toronto
The University of Toronto holds 12 patent records, the largest portfolio in the corpus, concentrated in B60L (electric vehicle propulsion), H02J (power supply and grid systems), and B60S (vehicle servicing). Its filings are characterized as a new entrant on momentum metrics, reflecting recent expansion into this specific application area. The university anchors the most active co-filing relationship in the field — seven joint filings with Havelaar Canada Industrial R&D Lab Ltd — indicating a deliberate commercialization strategy rather than pure research output.
12 patent recordsFermata Energy LLC
Fermata Energy LLC holds 3 patent records and its related entity Fermata Energy II LLC holds 4, for a combined presence in the B60L 53, B60L 55, and B60L 58 sub-classes, pointing to a focus on charging protocols, energy storage management, and vehicle-to-grid functionality rather than hardware. Both entities are classified as new entrants on momentum metrics. Rivian Holdings LLC holds 1 patent record spanning B60L 53, H02J 1, and H02J 3, representing the only large OEM presence in the corpus.
3 + 4 patent recordsFrequently asked questions
The evidence covers 20 patent families in scope. This is a nascent corpus, and the most recent filing years are likely undercounted due to standard patent publication lag.
The University of Toronto holds the largest portfolio with 12 patent records, followed by Eleappower Ltd with 11. Both are part of a Toronto-based academic-industry cluster.
The field is classified as Growth. Recent three-year filings are well above the prior three-year window, though annual volume has eased from a 2018 peak and the most recent years are further understated by publication lag.
The United States leads with 10 patent records, followed by Europe (EPO) and WIPO (PCT) with 3 each, and Canada and India with 2 each. Major Asian markets — including China, Japan, and South Korea — are absent from the evidence, representing a potential gap for companies targeting those regions.
The most-cited work relates to two title clusters: a ‘Device for bi-directional power conversion and charging’ (cited 31 times in the top-cited list) and multiple records titled ‘Systems and methods for an on-board fast charger’ (cited 15, 11, 4, and 2 times respectively). These represent the foundational prior art that new filings would need to address.
G05B (control and regulating systems) has only 1 patent record in the corpus, and H02P (control of motors and generators) has 6 — both sparse relative to the visible B60L and H02J classes. System-level charging control and integrated motor-drive-charger architectures appear underrepresented given their technical relevance to micromobility applications.

Patent data carries inherent limitations: recent filings (typically the most recent 18–24 months) are under-counted due to standard publication lag; counts may be reported at either a patent-family or a patent-record basis and are not always directly comparable; classification, applicant-name, and citation data may contain errors, duplicates, or omissions; and the underlying search query defines and constrains the scope shown.
